Microscopic and spectrometric characterizations of trace evidence materials present on the discharged lead bullet and shot—A case report

الملخص EN

Adherence of target materials or those present on the trajectory of the fired projectile is most common in the offences involving the use of firearms.

The recovery and identification of such adhering materials from a projectile may identify the origin or intermediary objects while fixing the trajectory.

In numerous cytological preparations, black deposits, contaminated debris from the bar-rel, perforated materials would be present on the target irrespective of the range i.e.

either distant or close.

All these must fully compliment and only such results are to be considered in the trajectory reconstruction.

The crucial role played by such trace evidences in the reconstruction of scene of crime in general and in the trajectory of the projectile in particular has attracted high levels of appreciations both in the forensic science community and among the user agencies.

Despite, trace evidence still remain unexploited and the integrities of potentially valuable material as trace evidence present on the spent projectiles are often infringed by crime scene managers or often unknow-ingly destroyed while processing.

The process of recovery and identification of trace evidence will normally acquire fairly high degree of complication as the discharged projectile would acquire them from their interaction with the intermediate targets.

Authors herein report two cases in that trace.
